Revelation 18:9-10

9  And the kings of the earth, who have committed fornication and lived deliciously with her, shall bewail her, and lament for her, when they shall see the smoke of her burning,

10  Standing afar off for the fear of her torment, saying, Alas, alas, that great city Babylon, that mighty city! for in one hour is thy judgment come.

The kings of the earth have a great time with this phony god and the world government and world trade that he sets up. They will become truly upset when she burns.  These same kings that now lament Babylon rejoiced when Mystery Babylon burned in chapter 17. Therefore, the two Babylons could not be the same. “ Mystery Babylon” of chapter 17 is religion that played the harlot with satanic paganism but “Babylon the Great” described in this chapter is a world political, economic and religious system that includes forced worship of the Beast as God.

These kings will not get near her when they see her judgment and see her burn with fire. This implies there is absolutely nothing at all they can do. The “ great city” described is the rebuilt golden city of the Antichrist Beast that will be built at Babylon in Iraq. This city is the actual final seat of the Beast kingdom of the end times, but the judgment illustrated by this judgment on an actual city also comes on the cities of the whole world. Revelation 16:19 tells us that all the cities of the world will fall at the time of Babylon’s destruction. What occurs at this time is the seventh vial judgment.
